Application led March 30, 19.26. Serial No. 98,473.

This invention relates to folding 'boxes or shipping containers.

The general object of the invention is to provide an improved double side wall box blank construction of that type having one closed end and which is adapted to be easily and quickly folded into a strong shipping container.

In particular the invention contemplates l0 in a box of this type the combination with side walls on the bottom and top, of foldable connecting gussets between the adjacent ends of the side walls and connected to the closed end; of flaps on the yfree ends of opposite 13 side walls adapted to be interlocked with each other to connect the opposite side walls se-/ curely together and to form a strong closure for the. open end; and the combination with the bottom of the box of an additional closure for the open end of the box with a tuck-in tab for holding the top and bottom of the box together.

The foregoing and other objects are obtained by the box illustrated in the accompanying drawings and described below. It is to be understood that' the invention is not limited to the specific form thereof shown and described.

Of the accompanying drawings: Figure 1 is a plan of the box blank; Figure 2 is a perspective illustrating the blank partly folded y Figures 3 and 4 are respectively longitudinal and transverse sections through the box during a further stage of the folding process; 4 Figure 5 isa perspective showing the box after the tabs on the top side wall have been interlocked across the open end; and Figure 6 is a perspective of the completely folded'box.

Referring to the drawings, 1 is the bot.- tom of the box, 2 the top, 3 the closed end and 4 the closure for the open end. These four elements of the finished box are ar ranged in a line through the center of the blank, the closure 4 carrying a small tuckin tab 5 which is also in line with vthe'four partsjust described. At thev sides of the bottom 1 are the parallel side walls 6 and at the sides of the top 2 are similar parallel side walls 7 which, for the sake of distinguishing, may be termed the bottom and top side walls respectively. At the sides of the closed end 3 are located the gussets-8 which lie between the side walls 6 and 7 and are preferably scored by crossing diagonal scorings 9 to facilitate thefolding of the box. This scoring may be of any preferred form so that the gussets will fold properly. In the form illustrated, thereis shown a species of scoring such as covered -in my prior Patent No. 1,230,675r of June 19, 1917. The gussets are rectangular in shape, but do not extend quite to the edges of the side walls between which they are located, the outer edges of the gussets thereby not interfering with the folding of the box.

On the free ends of the side walls flaps l0 70 are provided, these flaps being formed with inner edges 1l cut at outwardly directed an? gles so as not to interfere with folding operations and formed with notches 12 cut in-' wardly from the edges of the flaps 10 so that 75 when the side walls are turned upwardly one flap 10 will have a downwardly directed hook-like tab 13 thereon and the o posite iiap l0 will have an upwardly directed) hooklike tab 14 thereon whereby tabs 13 and 14 80 may be interlocked as shown at the right ends of Figures 2, 3 and 5.

In folding the box, the first operation is to bring the side walls at right angles to the blank to the position shown in Figure 2` 5 along the lines'20. ,'The flaps 10 on the bottom side Walls 6 are then folded inwardly and interlocked as shown. The bottom side walls 6 arenow held by the thumbs and second fingers while pressure exerted by the first fingers upon the gussets 8 causes them to fold along. the scored lines 9 and'brings the top over the bottom of the box, the top side walls enclosing the bottom side walls as shown in Figures 3 and 4. When the top is 95 brought down the flaps l0 extend forwardly of the open end. These are then folded inwardly and interlocked as shownv in Figure 5. It is to be noted that the flaps 10 on the bottom interlock in opposite directions across the open end from the iaps 1() on the top, whereby thefbox is effectively strengthened Iagainst a transverse diagonal colla sing action. The closure 4 is finally foltfied upwardly and tab 5 is tucked into the slit .105 between the outer edges (now the upper edges) of the top side wall flaps 10 and the top 2 thus securing the bottom to the top.

It will be understood that the goods to be packaged are placed on the bottom of the n box when the latter is foldedin the condition shown in Figure 2, the remaining folding operations serving completely to enfold the goods in the box. V 4

The box formed in the manner stated is easy and inexpensive to manufacture and Will securely hold when in folded condition. The invention is not necessarily limited to the utilization of every feature in a single box, as some of them may be utilized without all of the other features. Accordingly modifications of the invention may be resorted to without departing from the spirit thereof or the scope of the appended claims.

What is claimed is:

1. A folded box made from a one-piece blank comprising a sheet of material having defined therein a top, closed end, bottom and a closure for an open end in a line through the center of the sheet, top and bottom side walls laterally of the top and bottom, re-

` spectively, gussets between the top and bottom side walls, said gussets being scored so as to fold inwardly, flaps on the free ends of the side walls, and opposite flaps being formed with notches providing interlocking hook-like tabs for connecting the opposite side walls, the tabs on the top side wall flaps interlocking in reverse directionacross the open end from the tabs on the bottom side walldiaps, said closure for the open end having a tab thereon adapted to be tucked in between the outer edges of the remote flaps and the top for connecting the bottom to the top.

2. A folded box made from a one piece blank including a top closed end, bottom and a closure for an open end in a line through the center of the blank, top and bottom side Walls laterally of the top and bottom respectively, aps on the free ends of the side walls at both ends of the blank, opposite flaps being formed with hook-like tabs for connecting the opposite side walls, said tabs interlocking in reverse direction.

8. A folded box made from a one piece blank including a top, closed end, bottom vand a closure for an open end having a securing tab on its free end, the above elements being arranged in a line through the center of the blank, top and bottom side walls laterally on the top and bottom respectively, diagonally foldable gussets connecting the top `and bottom side walls, and flaps on the free ends of both the top side Walls and bottom side walls, said flaps being formed with hook-like tabs adapted to be interengaged to hold the side Walls in folded positions, the interengaged flaps of both the top and bottom side walls being adapted to overlap across the open end of the box and to be engaged by the tab on the closure for s aid end whereby the box is effectively se- Cured in folded position. y
